Reflection: How to retrieve index of map

[Mark Bauermeister]

I have the following code, where the TokenMap struct is actually part of another package. 
idMap is not exported and thus not accessible without reflection.

Through reflection I can easily find the value of "int", which is "28".
Now, I'd like to do the opposite though. I'd like to find "28"'s index (i e "int").

How would I go about that?

You can use the Index method on reflect.Value if it is an integer-
indexable type.
